This inventionhas reference to substantially spring acting means for the detachable mounting of signs or designationsbeari-ng plates or the like oninsulated electric conduits or conductors, and it is'intended to provide a device of the character described which may be readily sprung into position on the conductor, and may be retained at a certain point thereof by suitable stopping means, 10 and is thereby and bythe particular shape of its members secured against accidental disconnection. Broadly considered the device comprises aspring 7 acting clasp mounted astride of the conductor and provided with .ing suitable stopping means and adapted for the spring acting engagement oi coriesponddiate portion it snugly encirclesthe electric conductor, while itsfree spring-acting outer legs are bent at an inclination and away from eaohother. These legs are-ada-ptedto engage with the correspondingly inwardly inclined legs 0 of-the sign-bearing plate or bar 6 which is retained in position and secured against" accidental disconnect on by the spring action of the outwardly spread legs of the clasp a,

said legsbeing compressed by the legs of the sign-plate Z) in engagement therewith. The

spring legs of the clasp care provided with projections or longitudinally extending tabs or bending of a portion of the plate, metal band or the like of whichthe clasp a is formed. These tabs d or projections constioutwardly and angularly spread legs carryd which may be formed by the turning over tute stops for the axially displaceable clip I),

0, and in the preferred construction shown in the drawing said tabs or the like d are con-' frontingly disposed at the insides of the spring legs of the clasp, so that they are hearing against the sign-plate Z) itself, while if arranged on the outside of said spring legs PATENT OFFICE.

they would beliable to throw the legs 0 of 1 the plate out of engagement with the spring legs; The sign-plate or the like is by this I means securely clamped to the electric cable or conductor in such a mannerthat it will stay in its position even upon the'conductor itself being detached from the clasp or the like. The sign bmay carry the designation of the particular conductor with the possible characterization of'the phase preferably ona colored back-ground or in any other suitable manner, and it maybe so shaped and constructed that it may carry signs an'dinscriptions on its angular extensions 0 likewise, and the section b may be of multi face'd configuration. It may consist of thermoplastic, compressible material or be made in any other suitable manner.

It is of course to be understood that the de- Vice is not restricted to the particular configuration and arrangement of parts herein shown by way of example and illustration of ts'mode of operation only, but that it is sus-,

rounding the conductor and engageable with i the sidesthereof, spring-acting legs on said clasp angularly extendmg away and at an inclination to each other outside of the conductor, a sign-bearing member, angular exT tensions on said member inclined towards each other and detachably engageable with the spring actinglegs, 'confrontingly, disposed tabs at the. insides of said legs and adapted for engagement with thesign-mem; her. i
